Urinalysis, Complete, with Reflex to Culture [3020X]
10 mL random urine submitted in a UA Transport Tube (yellow-top, blue fill line, preservative tube)
Minimum: 4 mL of random urine submitted in a (gray-op) Urine Culture Tube
UA Transport Tube: 1 mL
10 mL random unpreserved urine submitted in a sterile, leak-proof urine container
The following criteria will be used to trigger a reflex to culture, which will be performed
automatically at an additional charge:
Presence of bacteria AND the presence of WBCs (> 5/hpf) OR leukocyte esterase
Presence of nitrite AND the presence of WBCs (> 5/hpf) OR leukocyte esterase
Presence of leukocyte esterase alone
Presence of WBCs (> 5/hpf) alone
Presence of yeast
Cleanse the urethral/glans area with soap and water and rinse with wet gauze pads. Encourage mid stream samples to minimize contamination and improve accuracy. Label the sample appropriately and store at room temperature until pick-up.
Note: The yellow-top, blue fill line tube cannot be used for collection and transport of specimens for urine culture.
Submit two separate specimens:
1). 10 mL (1 mL minimum) urine in urinalysis transport tube (yellow-top, blue fill line, preservative tube).
2). 4 mL (fill to minimum line printed on tube; unpreserved for Cultures 0.5 mL minimum) urine in urine culture tube (gray-top) tube.
Other acceptable specimen type:
Specimens not submitted in urine preservative tube (specimens from long term care and/or pediatric difficult collections only).
